Golf swing grading software system, golf swing component scoring chart and method

ABSTRACT

In accordance with the preferred embodiment and alternative embodiments described are embodiments of a system and method that automatically grading a golf swing, by grading components of a golf swing, relative to a perfect swing.

BACKGROUND

Golf teaching methodologies are numerous, as are devices that seek to attempt to instruct the particular golfer on how to achieve better results. Many of these methodologies are published in books and magazines, with pointers provided to the individual golfer on how to improve that golfer's score when on the golf course.

Also known are a myriad of teaching devices, aimed at assisting the golf instructor to teach the golfer. A simplest is an unused golf club that lies on the ground and which can be used to show a direction to a target.

Television coverage will also provide after the swing highlighting to a particular aspect of the swing of a professional golfer, suggesting why a particular shot was good, or, more likely, bad.

In play, the golf score is achieved by adding together the different shots taken. The lower the score, the better the round; and the better the golfer.

Along with the different golf teaching methodologies referenced above are various beliefs on what is necessary for a good golf swing.

SUMMARY

Described herein are embodiments of a software system that automatically grades a golf swing, by grading components of a golf swing, relative to a perfect swing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments and applications will now be described. Other embodiments may be realized and changes may be made to the disclosed embodiments. Although the preferred embodiments disclosed herein have been particularly described as a software system, score card, and methods of teaching and grading swing components, it should be readily apparent that they may be adapted.

In the following description, a reference is made to the accompanying drawings which form a part hereof and which illustrate several embodiments. It is understood that other embodiments may be utilized and structural and operational changes may be made without departing from the scope of the descriptions provided.

Overview Three Positions

Golf swings have a Start ‘position’, a Top of Swing ‘position’ and a Finish ‘position’.

There are not six, eight or ten, ‘steps’, or ‘check points’ that are important in a swing, but three and only three. Accepting this early concept—that a golf swing has only three positions—is important if, as we attempt to move forwards, we are to make progress towards certainty. I am not talking about certainty of performance, but certainty of understanding, of boundaries, parameters, dimensions, volumes, co-ordinates, structure, etc. None of these things will be possible if the concept of a swing is left as something non-specific or non-measurable. The golf swing is regularly simplified with casual ideas that are almost always found to be shallow when probed, either by question or by practical trial.

To suggest that golf and the golf swing is:

-   -   a ‘hands game’     -   a ‘turn back and turn through’     -   a ‘swing’ (very simple but non-specific, obvious, and helpful         only at a most basic level)     -   an ‘arms driven game’     -   a movement governed by the ‘feel of the club head’ (abstract and         non-transferable) . . . .         . . . or any other such similarly vague idea—is unsatisfactory.         Casual ideas like these may have some value at certain junctures         and for certain people but ultimately they lay down nothing that         is definite about what is a correct golf swing. Whilst a given         person may apply one of the simple ideas above, to their game,         and manage a transformation in play; the value that the same         idea might bring to the masses upon a test of validation would         be modest indeed. They are simply too vague.

So this overview begins by laying down an early parameter to help define the golf swing, and that parameter is:

‘As the club passes around the body at high speed, it is harnessed within three positions.’ (The three positions, in closer detail, will be further described hereinafter. Here they are being introduced as a central concept.

Impact is not a position: Impact is a moment that is passed through and it is beholden to the quality of the surrounding ‘swing fabric’, ie pre-impact and post-impact. If this surrounding fabric is flawed, then impact must also be flawed. However, due to the instructional focus historically placed on the impact moment in the swing and the impressive images thereof that are routinely presented, ‘impact’ is conventionally treated as a separate position, and one that is often held as being causal of poor shots. It is a mistaken understanding.

Impact is the single most important moment in the swing, and it is true to say that work can, and indeed must be undertaken on impact, during the route from learner to expert player. However, if this work is to be undertaken effectively, it should be done through the use of a ‘strike thought’ or ‘strike concept’, one that would be intended to create a change to impact's physical dynamic. Any attempt to improve impact by way of treating it as a position, will falter. This is because when dealing with strike as a position the body will want to momentarily stop to ‘create’ the position, and even if this impulse is fleeting it will nevertheless have a damaging effect.

Thus, if we want excellence in the impact area, then, we must employ the use of simple strike concepts such as ‘hit down’, or ‘hit through’, plus (and this is the most important aspect) we must pursue a tightening of the aforementioned swing fabric that surrounds impact and ‘trap’ impact into proper form. This is where Three Positions has great importance, for it is through these that the trapping begins.

Each of the Three Positions has a number of components. A component is a part of the body that has independent aspect during the swing; that is, it does not automatically position or move correctly, but needs training.

For example, the left arm when in the Top of Swing position is deemed to be a component because it will not automatically be on the correct ‘plane’ after its journey to the top. Neither will it automatically have correct ‘form’ when it arrives there. What is more, there is nothing you can do elsewhere with the swing or with the body to guarantee influencing it into correct form or placement. It has independence from other body parts and so has ‘independent aspect’ during a golf swing. This is why left arm is deemed to be a component and is also why it needs separate study and training.

Another example of a ‘component’ would be a player's head set, which has a discipline to perform in each of the Three Positions, and, when in the Finish position, it should be seen to be tilted on its side and facing the target. As before, nothing you can do elsewhere in the swing will provide delivery of head set into correct form at Finish. It is independent and lust like other components, needs separate training.

The grip, is of course; another component. However unlike the headset, which has a task to perform on three occasions, the grip is only a component on one occasion—in the Start position. Once the grip has been set correctly in Start, it stays in place for the rest of the swing and no longer has independent aspect. It is fixed.

Each of the Three Positions ‘Start’ ‘Top of Swing’, and ‘Finish’ have a number of components that define them, in one embodiment there being the following number of components:

Start position—7 Top of Swing position—10 Finish position—8

All golf swings have these 25 components. The status or grade of these components determines the status/grade of the swing itself, and the strictness of the arrangement of the 25 components is the determining factor in whether a player can be said to have good technique, or not.

Point to point

Some people believe that the swing is best learnt when built painstakingly, almost inch by inch. Most of us do not undertake such a difficult task, but do however use the same principle; that of adding a piece to a piece or a section to a section with great care until the swing is slowly built. This is a perfectly fine and normal approach. The following is incomparably better though, as it is apparent that:

‘The body can be left free, and be trusted to find route from one place to the next, so long as it knows where the next ‘place’ is.’

Furthermore, ‘The body's innate skill will seek out the most intelligent route forward—always.’

If we adopt this idea and apply it to the three positions described above—then Point to Point states that after the player has taken up their Start position, the swing should be left alone to make its own route to the next position—Top of Swing. Likewise, once the player departs Top of Swing position, the swing should again be left alone to make its own route to its next position—Finish. When the player allows this to happen the swing is able to ignore and bypass ‘stations’ check-points' or ‘steps’ that would otherwise interfere with and disturb, smooth movement.

Point to Point is—‘The free and untouched passage between two positions’

Auto-Neuro Response

Point to Point, as a concept, assists in achieving the highest status in Quantum Golf Swing Theory described herein. It has a right to this status because of the power of the principle that underpins it. Point to Point says that the body should be left free to move by itself from place to place. We will now open that idea fully and explain exactly why we should hand over the control of our golf swing, and the principle on which this is based is described herein as Auto-Neuro Response, which is based upon the proposition that ‘The human body, moving under jurisdiction by way of a set of parameters, will seek out the most efficient means of movement, whilst obeying those parameters’.

The parameters in golf are the Three Positions that the player will visit during the swing. The status of a player's positions, and of the components within them, does not affect the ANR mechanism in any way. Auto-Neuro Response is ready to respond if allowed no matter who the golfer is and no matter how good or bad their swing is. When a player has numerous component errors in their swing, then those numerous component errors become the ‘parameters’ that ANR will register and work with. Consequently, if there is a ‘tangle’ it will recognise it and proceed to the next ‘tangle’ (if that is what lies ahead) as efficiently as possible.

One thing that is interesting is that the numerous component errors in any given swing are seen by observers to repeat to a surprising tolerance (considering the array of shots hit) and this repeating swing and repeating tolerance is consistent whether the player plays from a handicap of eight or eighteen. The fact that one moment a fine shot occurs and the next moment an awful one, is in no way representative of the player finding a fine swing one moment and the next, the opposite. The very same swing that hits it beautifully to the pin, also, duffs it into the lake. Components in the swing of both the beautiful shot and the duff shot will be the same, but with a random element in timing and strike and the increased factor of chance that a poor technique is vulnerable to. In both instances though and in every other instance imaginable, Auto-Neuro Response will deliver the best possible movement from whatever is given to it by way of the Three Positions, and no amount of effort by a player to consciously manipulate or co-ordinate the move can compare to the performance ability of their natural ANR mechanism.

Conscious attempts made to hit ‘steps’ or ‘check-points’ during the golf swing are misguided. There is an infinitely more intelligent system, innate, and ready to deliver safe movement, from one place to the next.

Swing-Thoughts

A swing-thought is a consciously inserted ‘thought’ or ‘awareness’ that the player focuses on during the swing in an attempt to bring about a successful shot. Thoughts or awareness' prior to the beginning of the swing are not swing-thoughts. A player may simply be ticking off a check-list when thinking in the moments leading up to the take-back and the best we could say for any specific thought at this point in proceedings is that it is hoping to act as a primer. Sometimes two or more swing-thoughts are employed during one swing, but this is not recommended, at least not during competitive play.

The most common use of a swing-thought is as an attempt to apply compensation to an error that repeats in a player's swing. A game of golf is often littered with poor shots. When we finish play and shake hands there will usually have been half a dozen or more shots hit, that we wish we could have another go at. Some shots are so dire that our score is badly affected by them, and if these particularly bad shots repeat a few times, then the score can be ruined.

So, as golfers, we will all have passages of play (lasting weeks or months) during which a repetitive error will arrive that becomes the main concern and the main problem, to be fixed. What will usually happen next is that an analysis will be undertaken by the player, and a fault will be found that apparently accounts for the bad shots being hit. Having thus diagnosed the fault, the player then searches for a corresponding swing-thought that can be employed to counter, or correct, it. At this point in proceedings what looks like being a promising and proactive response can suddenly hit a wall of difficulty, for the following reason: The particular swing-thought that the player might decide to employ, could be very well chosen and highly relevant, but it needs support from the component that is linked to it and support therefore from at least one, of the Three Positions. If the player's component grades do not support the intended move, then the intended move will fail—again and again—to take hold in the player's swing. In the main, this is the reason why so many players have difficulty delivering a success from a determined effort with their swing-thought. Their component grades are not compatible with what they are attempting to do. Once, though, the player has corrected the component/s relevant to the given move then they will be able to find success with their swing-thought. This is the real significance behind ‘components’, they allow for and even encourage proper movement of the club to take place. If a player does not have well graded components that suit the chosen swing-thought, they will be engaged in an on-going struggle against the dictates of their swing's fundamental status.

Components are thus so influential as to be vital to the success of a golf swing, including to the success of a swing-thought. Their authority and influence is such that we can say—‘When something truly fundamental is in error, or is flawed; it necessarily brings damage to all things connected’.

In this case ‘all things connected’ includes the player's well-intended swing thought, the one that they are trying to make happen, but which is not being supported by the grade of the component associated with it.

Swing-thoughts are, and always will be, a part of golf. They are a must-have tool for the vast majority of golfers. What is described herein is not trying to minimise their place in the game by the above understanding, for they deservedly have a place of great importance in the game. Just their dependence is being declared.

With the above introduction, reference is not made to the drawings and other descriptions that describe embodiments herein.

FIGS. 1A-1C each illustrate one of the three positions from which component information is obtained according to embodiments described herein. These positions are shown as the start position in FIG. 1A, the top of swing position in FIG. 1B and the finish position in FIG. 3C. In between the start position and the top of swing position is a movement well known as the backswing. In between the top of swing position and the finish position is the ball strike movement.

FIGS. 2A-2B illustrate components of the start position according to embodiments described herein. A golfer is shown in the start position, 200, gripping a golf club 202, which for purposes of the discussions herein is a driver, though other clubs could be used. The start position components 210, which will be described further hereinafter, include the grip-right hand 210-1, the grip-left hand 210-2, the ball position 210-3, posture 210-4 (which includes (knee bend) 210-4 a, posture (body angle) 210-4 b, posture (head set) 210-4 c, and posture (hips tilt) 210-4 d), arms 210-5 (which includes arm extension 210-5 a and arm straightness 210-5 b), feet 210-6 (which includes right foot 210-6 a, left foot 210-6 b and feet width 210-6 c) and alignment 210-7 (which includes shoulder alignment 210-7 a, and feet alignment 210-7 b). As will be explained hereinafter, where there are multiple different aspects to a component, individual scores for each aspect are obtained and then averaged in some manner to get a total score for that component.

FIGS. 3A-3B illustrate components of the top of swing position according to embodiments described herein. The same golfer is shown in the top of swing position 300, still gripping the golf club 202, at the top of the backswing. The top of swing position components 220, which will be described further hereinafter, include body turn 220-1, left arm 220-2 (which includes left arm plane 220-2 a, left arm form 220-2 b and left arm leverage 220-2 c), head set 220-3 (which includes down the line view 220-3 a and front view 220-3 b), right arm 220-4, wrists 220-5 (which includes wrist hinge one 220-5 a and wrist hinge two 220-5 b), body angle 220-6, hips 220-7, knees 220-8 (which includes front view 220-8 a and side view 220-8 b) and feet 220-9 (which includes right foot 220-9 a and left foot 220-9 b). As will be explained hereinafter, where there are multiple different aspects to a component, individual scores for each aspect are obtained and then averaged in some manner to get a total score for that component.

FIGS. 4A-4B illustrate components of the finish position according to embodiments described herein. The same golfer is shown in the finish position 400, still gripping the golf club 202, at the finish position at the end of the ball strike movement. The finish position components 230, which will be described further hereinafter, include body twist/wrap 230-1, body lean 230-2, head set 230-3, arms 230-4, wrists 230-5, hips 230-6, knees 230-7 (which includes right knee side view 230-7 a, right knee front view 230-7 b, and left knee 230-7 c), and feet 230-8 (which includes right foot 230-8 a and left foot 230-8 b).

Camera Embodiment System Overview

FIG. 5 illustrates one embodiment of a system that provides for a software system that automatically grading a golf swing, by grading components of a golf swing, relative to a perfect swing, based upon the use of digital video cameras, also just referred to as cameras herein. As an overview, this system 500 records an image or images of the golfer at each of the start position 200, the top of swing position 300, and the finish position 400. Then using these images, specific component values are determined and summed to obtain an overall swing score, with a scoring system that has, preferably, a highest score being a perfect swing, though of course other scoring systems can be obtained based upon the discussions provided herein.

The system devices that work together in the embodiment described include front camera 510A, side camera 510B, and top view camera 510C, which provide different views of the golfer, respectively. Other camera angles can be used, as well as even a single camera (in which case it would be front vie camera 510A), though likely with some degradation on the ability to best capture each of the component positions described herein. The cameras 510 are preferably video cameras; since although a single picture is preferably used during analysis as described further herein, having continuous frames, and then later selecting the specific best frame, as further described herein, is preferable.

Connected to the cameras 510 is a computer 520, which includes an input output (I/O) port(s) 512(a-c) for connection to the cameras 510 (A-C), as well as a display 530 and an input device 540, such as a keyboard. Other types of computer devices can be used as well. The computer 520 preferably contains a CPU, memory (including system memory, program application memory, data memory, other data storage in RAM, ROM, transitory and/or non-transitory memory, as well as registers and the like) and other conventional hardware for connections to the swing capture devices, the display, the input device, and other devices for communications connections (such as to the internet) and the like, as well as allows the loading of an application software program containing program instructions, executed by the computer along with the operating system software, that enable the functionality described herein, including in the following flowchart of FIG. 6 and the component descriptions detailed hereinafter, and which can also include data manipulation and transformation algorithms necessary to operate upon the various different data as described herein.

Camera devices 510 can preferably be connected to allow for the camera to receive signals from the computer 520 regarding their specific positioning, since while positioning can be performed by hand, automatic control based upon the size of the golfer and other considerations as discussed herein is preferable.

FIG. 6 illustrates a flowchart used in the embodiment of FIG. 5. In enter user data step 610, the input device 540 is used to input user data, particularly the height of the golfer, as that is most relevant to correlating actual and predetermined gofer data, as discussed further hereinafter.

In configure for the user step 620, correlations are obtained so that subsequent component data obtained with respect to the particular user can be more easily correlated to the predetermined ideal golfer component data stored on the computer, based upon the input user data—though techniques may also exist that eliminate the need for this step. In an embodiment where the subsequently obtained start position component data, top of swing position component data, and finish position component data is calibrated to the predetermined ideal golfer component data, actual-to-ideal scaling factors can be applied to the different types of start position component data, top of swing position component data, and finish position component data in order for them to correctly match the scale of the predetermined ideal golfer component data. In an embodiment where the predetermined ideal golfer component data is calibrated to the obtained start position component data, top of swing position component data, and finish position component data, ideal-to-actual scaling factors can be applied to the different types of ideal golfer start position component data, ideal golfer top of swing position component data, and ideal golfer finish position component data in order for them to correctly match the scale of the obtained start position data, top of swing position data, and finish position data, respectively. Other embodiments using sensors with detectors or other data collection techniques can be scaled as well, based upon the teachings provided herein.

Thereafter, once the system 500 has preferably been configured for the specific golfer, steps 630, 640 and 650 occur, start position images, top of swing position images, and finish position images are obtained, respectively. The images associated with each different position are preferably time correlated, such that a different image obtained from a different camera for the same position (start, top of swing, finish) are synchronized as to time.

As to which time-stamp image to use in the sequence of video images of the user, the start position images are each obtained from that time that just precedes detectable backswing movement, though in light of the large number of sequential images obtained by a video camera, any number of prior, or even a few frames immediately after swing start, could be used. The video image can be analyzed using, for example, conventional motion detection techniques, template matching or lookup table pattern matching applied to the received video stream. As a specific example, techniques such as those used for animation can be applied to the different obtained images, so that distances between various points of interest, to obtain the various angles and distances necessary for the correlations described herein. An example of such an animation model is described in U.S. Published Application 2010/0259546, entitled “Modelization of Objects in Images”, the contents of which are expressly incorporated by reference herein.

It is also possible, for use with the video image and the camera as described herein, to include markers that are attached at various points (which points correspond to the location of the sensors described hereinafter in FIG. 7, in order for the overall model development of significant movements, as is described, for example, in U.S Published Application 2012/0002017, entitled “Three-Dimensional Motion Capture”, the contents of which are expressly incorporated by reference herein.

Another technique that can be used is to create a skeletal model based upon the image, as described in, for example, U.S. Published Application 2012/00588824 entitled “Scalable Real-Time Motion Recognition.” the contents of which are expressly incorporated by reference herein.

Still another technique is disclosed in U.S Published Application 2011/0210915, entitled “Human Body Pose Estimation”, the contents of which are expressly incorporated by reference herein.

The above different techniques make it apparent that a wide variety of techniques can be used in connection with the embodiments described herein, and still be within their spirit and scope.

Regarding the corresponding ideal golfer video image or corresponding ideal golfer component data associated with that start position, a single start image photo of the ideal golfer, such as Rory Mcllroy or Charl Scwartzel, can be obtained; if necessary, adjustments can be made to the relative ideal golfer component values to obtain the ideal data set, though a data set based upon the swing of either of these two golfers would be more than adequate.

Each top-of-backswing position image is obtained from that time that amounts to the rest position at the top of the backswing, immediately at the end of the backswing, and right b before the beginning of the downswing, with room for slight variation as discussed above. The continued video image can be analyzed for the top-of-backswing position images using the same conventional motion detection technique as previously used and described.

Regarding the corresponding ideal golfer video image or corresponding ideal golfer component data associated with that top-of-backswing position, the top-of-backswing position will differ significantly from golfer to golfer with respect to its size/volume. To accommodate for this, this embodiment preferably first automatically obtains the top-of-backswing position image for the actual golfer being analyzed. Based on the relative size of backswing, a corresponding position for that amount of backswing is automatically retrieved from a stored database of images/component values for the ideal golfer top-of-backswing position. In one embodiment a predetermined ideal golfer image/component data set exists for every 1° of rotation of the wrists from a 0° start point of a video sequence of the ideal golfer taking a backswing, such as Sam Snead or Rory Mcllroy as described above, through 180 degrees to the ideal top of swing position. If necessary adjustments can be made to the relative ideal golfer component values to obtain the ideal data set for the entire range of top-of-backswing images/component values, though a data set based upon the swing of either of these two golfers would be more than adequate. Depending upon the degree of rotation of the actual golfer, the corresponding predetermined ideal golfer image/component data is selected for the comparison use as described herein below.

Each finish position image is obtained from that time that amounts to the end of the throughswing, when the arms/hands finish their progression around the golfer, as seen from the front view, with room for slight variation as discussed above. The continued video image can be analyzed for the finish position images using the same conventional motion detection technique as previously used and described.

Regarding the corresponding ideal golfer video image or corresponding ideal golfer component data associated with the finish position, a single finish image photo of the ideal golfer, such as Rory Mcllroy or Ben Hogan, can be obtained; if necessary, adjustments can be made to the relative ideal golfer component values to obtain the ideal finish component data set, though a data set based upon the swing of either of these two golfers would be more than adequate.

Once the image has been obtained that will be used to determine the corresponding component data and the corresponding image/component data for the ideal golfer, the system in step 660 will calculate the component score, based upon automatically derived associated component data and corresponding ideal component data, as discussed hereinafter.

The component data automatically derived from a particular image for a particular component is described in detail hereinafter with respect to each component, and this is used with respect to obtaining the ideal golfer component data set, as well as the component data set for the golfer being scored. In common between all components, however, is that once the component data from a particular image for a particular component is automatically derived, the system 500 will then compare that component data with the corresponding ideal golfer component data for that component, and automatically determine how close to the ideal that particular component was, and therefore provide a relative score associated therewith for that component.

Well known and understood image processing techniques can be used determine the component data of the golfer who is being measured based upon the descriptions provided hereinafter, and then comparing that against the predetermined ideal golfer component data to obtain the score for that component. In general, the more the overlap between the measured component data and the ideal component data, the higher the score.

It is noted that the determination of the component data for each different component is preferably based upon a single image, as this eliminates the need to cross-correlate images obtained from different cameras in obtaining the component data for any one component, and ultimately makes it easier to obtain the component score for that one component.

A preferred component scoring system can have, for example, a component score of integers between 0-10, with 0 being the worst and 10 being the best, though other scoring systems having less or more score granularity can be used and is within the intended scope of the embodiments.

After the scores for each component are derived in step 660, they are automatically summed by the system 500 in step 670 to obtain a swing total, which is then preferably displayed on the screen 530 in step 680.

It is noted that in the above system each of the components are equally weighted. An alternative that is within the scope of the embodiments is to weight the more important components (described as such in other places herein) more importantly than others, in order to obtain a total score that is skewed toward recognizing the importance of significant components.

Regarding the component data described above and described in more detail below for specific components, the scoring system for each component is described as being based upon a single swing. Of course, multiple swings can be analyzed, the system 500 configured to provide and average of the total swing score, as well as averages for each particular component.

The body angle component 220-6 below describes the measurement and corresponding point score for the body angle which is given whole component value it top of swing position (as opposed to start position where it is a sub-component) and is best measured using the side view camera 510 b. Reference is also made to FIG. 10A that illustrates that this angle (though in the start position rather than top of swing position in the illustrated Figure) is determined by a straight line drawn between the reverse most (back of player) point of the belt or hips and connecting to the rearmost point of the golfer's neck. The method of measurement taken for body posture sub-component in start (0070), is also used for measurement of body angle in top of swing position. Body angle at top of swing position should have remained the same as at Start position. Therefore the same data is relevant and applicable.

Table XIII provided below describes the measurement and corresponding point score for the body angle component 220-6 and is best measured using the side view camera 510 b.

The angle is taken from a ‘down the line’ view and is determined by a straight line drawn between the reverse most (from front) point of the belt or hips and connecting to the rearmost point of the golfer’s neck. (See diagram) Each +/−1″ in height equals +/−½ of one degree in body angle adjusted to find the players 10 grade. i.e a player 5 feet tall will have a 10 point grade for a 39 degree bend. Hips component 220-7

The hips component 220-7 is determined in relation to a vertical line dropped from the edge of the right hip from the front-on view, and then in relation to the hips original position when at start, as shown in FIGS. 17A and 17B.

These above component descriptions, while described specifically with respect to the camera embodiment, are equally applicable to the sensor embodiment described hereinafter, and the measurements made can be readily determined using the different sensors described hereinafter.

Further, it should be understood that a combination of a camera embodiment and a sensor embodiment can also be used.

SENSOR EMBODIMENT

FIG. 7 illustrates one embodiment of a system that provides for a software system that automatically grades a golf swing, by grading components of a golf swing, relative to a perfect swing, based upon the use of sensors. As an overview, this system 700 records an “image” or “images” of the golfer at each of the start position 200, the top of swing position 300, and the finish position 400, as in the camera embodiment described previously. This “image” is essentially an overall pattern showing the location of different sensors, which location is relative to one another or a predetermined reference at a determined point in time. Then using these images, specific component values are determined and summed to obtain an overall swing score, with a scoring system that has, preferably, a highest score being a perfect swing, though of course other scoring systems can be obtained based upon the discussions provided herein.

The system devices that work together in the embodiment described include sensors 710 and detectors 720 wirelessly coupled thereto, which together allow for a determination of the three dimensional location of each sensor 710 relative to each detector 720, preferably at a rate which equals a detection rate similar to that obtained in the number of images used when obtaining a video from a video camera. As in the camera embodiment, the positions of the sensors 710 relative to the detectors 720 are continuously obtained throughout the swing, and start position, top of swing position and finish position measurements are determined, as described herein, to select the specific best time sensor measurements for use, as further described herein, is preferable. Sensor types can include, for example, infrared, GPS or other location sensing technologies. Connected to the detectors 720 is a computer 730, which includes an input output (I/O) port(s) 732(a-c) for connection to the detectors 720, as well as a display 740 and an input device 750, such as a keyboard. Other types of computer devices can be used as well.

FIG. 8 illustrates a flowchart used in the embodiment of FIG. 7. In enter user data step 810, the input device 750 is used to input user data, particularly the height of the golfer, as that is most relevant to correlating actual and predetermined golfer data, as discussed further hereinafter, although other user data can also be included, such as the length of the arms and legs of the golfer.

In configure for the user step 820, correlations are obtained so that subsequent component data obtained with respect to the particular user can be more easily correlated to the predetermined ideal golfer component data stored on the computer, based upon the input user data—though techniques may also exist that eliminate the need for this step, as described previously with respect to step 620 in the camera embodiment

Thereafter, once the system 700 has been configured for the specific golfer, steps 830, 840 and 550 occur, start position sensor data, top of swing position sensor data, and finish position sensor data are obtained, respectively. The “images” obtained due to the different location of each of the different sensors relative to one another (and specifically for those relationships needed to determine the components described above) are preferably time correlated, such that different sensor data (measurements between each sensor 710 and each detector 720) are synchronized as to time for the start, top of swing, finish position data sets.

As to which time-stamp sensor data to use in the sequence of sensor data, the start position data are each obtained from that time that just precedes detectable backswing movement, though in light of the large number of sequential time-stamped data sets obtained by the different detectors 720, any number of prior, or even a few time slots immediately after swing start, could be used. The sensor data can be analyzed using conventional motion detection techniques, based on three-dimensional sensors, which are applied to the received sensor data as described herein. Motion detecting sensing (which is used to determine which “image” or time for the location of the different sensors to use), as well as then the location sensing in order to determine the relationships between necessary sensors, are conventional. One example, however, is described at U.S. Application 2010/0152623, entitled “Systems, Devices and Methods for Interpreting Movement,” the contents of which are expressly incorporated by reference herein.

Regarding the corresponding ideal golfer sensor data or corresponding ideal golfer component data associated with the start position, that position and data can be obtained similar to the camera embodiment previously described, though based upon sensor data rather than image data.

Each top-of-backswing position image is obtained from that time that amounts to the rest position at the top of the backswing, immediately at the end of the backswing, and right before the beginning of the downswing, with room for slight variation as discussed above. The continued sensor data received in sequence can be analyzed for the top-of-backswing position using conventional motion detection techniques.

Regarding the corresponding ideal golfer sensor data set or corresponding ideal golfer component data associated with that top-of-backswing position, the top-of-backswing position will differ significantly from golfer to golfer, as the amount of backswing varies considerably from golfer to golfer. To accommodate for this, this embodiment preferably first automatically obtains the top-of-backswing position sensor data for the actual golfer being analyzed. Based on the relative degree of backswing, a corresponding position for that amount of backswing is automatically retrieved from a stored database of images/component values for the ideal golfer top-of-backswing position, as described with respect to the camera embodiment.

Each finish position sensor data set is obtained from that time that amounts to the end of the downswing, similar to the end of the downswing as described previously with respect to the camera embodiment. The continued sensor data stream can be analyzed for the finish position images using the same conventional motion detection technique as previously used and described.

Regarding the corresponding ideal golfer sensor data or corresponding ideal golfer component data associated with the finish position, that position and data can be obtained similar to the camera embodiment previously described, though based upon sensor data rather than image data.

Once the sensor data has been obtained that will be used to determine the corresponding component data and the corresponding image/component data for the ideal golfer, the system in step 860 will calculate the component score, based upon automatically derived associated component data and corresponding ideal component data, as discussed hereinafter. The component data automatically derived from a particular set of sensor data for a particular component is essentially the same as that described previously with respect to the camera embodiment, with difference in the implementation being slightly different due to the component data being obtained from the sensors rather than the image will have slight differences due to the form, but, as well be apparent, provide the same relative distance measures.

After the scores for each component are derived in step 860, they are automatically summed by the system 700 in step 870 to obtain a swing total, which is then preferably displayed on the screen 740 in step 880.

Regarding the sensors that are used, as mentioned, each sensor 710 is able to provide the relative three dimensional position of that sensor 710; as described here relative to each of the detectors 720.

Regarding specific sensors, the grip position 210 is determined from the wearing of a right hand grip wrist sensor 716 a (preferably worn like a watch) that allows the external detectors 720 to measure precise degrees of wrist rotation and from these degree references the grip can be graded.

Left hand grip position 220 is determined from the wearing of a left hand grip wrist sensor (preferably worn like a watch) with reflective surface that the external detectors 720 to measure precise degrees of wrist rotation, and from these degree references the exact knuckle score can be calculated and the score graded.

It should be noted that for components where a particular golfer obtains a low score, the system can provide a visual comparison of the position of the particular golfer's component to the ideal, thereby allowing for greater understanding of the error by the golfer.

FIG. 28 illustrates a score card usable to assist in grading the start position, top of swing position, and finish position components according to the embodiments described, for instances where a golf professional is teaching, and instead of using a camera, instead views the positions, and components therein, of the golfer. While the score card is illustrated with places to include both a raw component score and an overall score for each component, a modification of the score card would include only the column for the overall score, and not the raw component score column. The score card can also exist on a sheet that exists in paper and/or electronic form of a writable display screen, whereby the scores can be added into the appropriate cell locations on the card.

It is also understood that a number of different swings can be used, either with respect to the system 500 described above or with respect to a golf pro using his eyes and knowledge. For the latter, the score card as illustrated can greatly assist ensuring that all the component positions are accounted for.

It is also understood that one could modify the embodiments described above by adding more components or not using all of the swing components as identified herein. On possible combination of different components would include: for the start position, components related to ball position, posture, grip left hand, grip right hand, and feet; for top of swing position body turn, body angle, left arm plane, left arm form, writs and head set; for the finish position, body twist/wrap, body lean, arms, wrist and hips. Of course other combinations could be derived as well.

FIG. 29 illustrates an ensemble of clothing 1610 having sensors that are pre-inserted into the different clothing pieces and objects, which can be sold as a set with or separately from other equipment 1650 described herein, including the driver 1652 with sensors (such as club sensors 722 previously described in FIG. 7), ball 1654 with sensor (such as ball sensor 724 previously described in FIG. 7), alignment sensors 1656 (such as sensors 726 previously described in FIG. 7) and associated software and/or computer 1658, as shown. In particular is illustrated a cap 1612 that has includes head sensors 710(a-c) as previously described with reference to FIG. 7. Also illustrated is a sweater 1614 that includes shoulder sensors 712(a-b) and hip sensors 513(a-c) as previously described with reference to FIG. 7. Further illustrated is a pair of wrist bands 1616 that each has a wrist sensor 716(a-b) as previously described with reference to FIG. 7. Also illustrated is a pair of above-the-knee band 1618 that each has a knee sensor 718(a-b) as previously described with reference to FIG. 7 (alternatively, not shown, the knee sensor 718(a-b) could be sewn into a pair of pants). And included is a pair of leather overhang pieces 1620 that can each be tied to a shoe and each contains one of the sensors such as foot sensors 720(a-b) previously described with reference to FIG. 7.

Teaching aids can also be provided. For example, the system can provide a graphic representation pictorially illustrating why a particular component score was low relative to an ideal component score.

Software Game

In another embodiment is a software game, based on the grading system described above, and which can use the software described above, modified for the game as described herein, and particularly with reference to the patent applications incorporated by reference above that reference gaming. The game is played by a gamer who stands in front of a TV which has a camera mounted on top that faces the gamer, just as the cameras and digital display described hereinabove, albeit a simplified version that may have only a single camera, and may or may not have an additional sensor or sensors. The gamer makes a golf swing, not necessarily with a real golf club, but preferably a short golf ‘stick’, approximately 20 inches long, and preferably sensored to aid realism for the swing being made. The camera captures the three important positions that the gamer hits during their swing, as described above. The images are then interpreted through the software application according to pre-determined parameters put in place specifically for the playing of the game, preferably those as described above, and in line with embodiments described herein. Positions are then graded accordingly and the gamer is given a readout for each of their three positions, plus a read out for their important overall total, up to a maximum possible 250 using the grading system described above. It is the overall total that other garners have to try to beat.

The game is competitive, fun, and educational, in that the pre-determined parameters put in place for the game are representative of good technique. The gamer improves their real life golf swing by playing the game, and by striving for higher and higher game scores.
